CASE.

SPEGIFIGATION forming part of Letters Patent No. 281,294, dated July 17, 1883.

Application filed April 1'1, 1882. Renewed April 30, 1883. (No model.)

Tea/Z5 whom it may concern:

Be it known that I, EMERY PARKER, of New Britain, in the county of Hartford and State of Connecticut, have invented certain 5 new and useful Improvements in Lock-Gases; and I do hereby declare that the following is a full, clear, and exact description thereof, whereby a person skilled in the art can make and use the same, reference being bad to the IO accompanying drawings, and to the letters of reference marked thereon.

Like letters in the figures indicate the same parts.

My improvement relates to a new device for fastening castiron front plates to lock-cases; and its object is to provide a ready and efficient means of securing the front plate to the case without the use of screws or rivets or any extra parts or appliances for the purpose.

In the accompanying drawings, illustrating my invention, Figure 1 is a side View of a lock-case embodying my improvement, with the edge of the front plate removed so as to show the interior construction. Fig. 2 is a 25 longitudinal section of the front plate before being attached to the case. Fig. 3 is a back View of the front plate before being attached to the case. Fig. 4 shows a side and edge view of the wrought-iron clip which holds the parts together.

A represents a lock-case of any ordinary construction, provided with ears or projections A, for attachment to the front plate.

B is the front plate. This is madeto fit onto the lock-casein the customary manner, the back being recessed for the purpose of receiving the front edge of the case and the ears or projections A, so that these last shall lie nearly or quite within the thickness of the 40 plate B. The edge of the front plate is raised all around at B, so that its edge presents a uniform thickness and incloses the edge of the lock-case and the means of attachment. The foregoing parts are intended to be made of cast-iron.

G G are wrought-iron clips of the form shown in Fig. 4. They are placed in the mold when the front plate is cast, and are cast into it. The ends 0 enter under the edges B of the plate and hold the clip firmly in the casting.- U

The clips 0 are furnished with projections D, which are used to hold the clip firmly in the sand or other material in which the mold for the front plate is formed, and which are removed after the casting is made.

The ends of the front plate, B, outside of the clips can be made thicker than the mi ddle portion of the plate opposite the lockcase, for the purpose of supporting the clips better and giving a better bearing for the countersinks for the heads of the screws by which the plate is attached to the door.

Myimproved front plate is cast with the clips in the position shown in Figs. 2 and 3, and when the plate is attached to the lock-case the clips are bent down over the projections A, which unites the plate and case firmly together.

What I claim as my invention is- The combination of the front plate, B, recessed for the reception of the lock-case, the wrought-metal clip C, provided with end projections, G, by which it is cast into and held by the sides of the plate B, and the lock-case A, provided with the projections A, substantially as described.

EMERY PARKER.
